Feature Proposal: adjusting time according to refresh interval

[cherti]

Currently, i3status has a refresh interval and all widgets are updated according to this interval.

Assume, for the sake of argument, we use a tztime widget in the form hh:mm, showing hours and minutes of the current time and an interval time of 60s.
In this configuration, the clock is behind the actual time for a certain amount of time (varying from 1s to 59s, depending on how i3status' refresh coincides with the actual minute turnover).

For some people it is preferrable to have the tztime widget advance the clock instead of lagging behind.

This could be implemented in two ways:

1. introduce an optional bool-flag in tzdata and correct the time accordingly by the global interval value.
2. introduce an optional correction value to tzdata by which the clocktime can be adjusted.

Would either of these options be merged upstream?
